And no matter how many times FOSS developers are shown that real people don’t care about products with shitty UX, they won’t put time in making their product accessible.

See how that goes?

Wanna fix federated platforms? Make the backend dumb and the frontend smart. No one that has a life wants to learn about instances and all that bullshit, decentralize the storage and let anyone create a frontend where people can connect and check the content, one credential to access everything, defederation doesn’t affect the users, no admins just moderators.
